This invention relates to improvements in envelopes and to means foropening the same an ob ect being to provide an envelope novelconstruction having means whereby it may be opened without danger ofmutilatin its contents.

ith the above and other'objects in view, the invention further includesthe following novelfeatures and details of construction, to behereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claims. In the drawings: Figure1 is a view of the blank of which i the envelope is formed. 4

Figure 2 is a view showing the envelope partly-folded.

Figure 3 is an enlarged fragmentary sectional view on the line 3-3 ofFigure 2.

Fi 're 4 is a view showing the envelope just fore the bottom flap isfolded.

Figure 5 is a view of the. completed envelope partly broken away.

F1 are 6 is an enlarged fragmentary sectiona view on-the line 6-6 ofFigure 5.

Figure 7 is a fragmentary view of a portion ofthe envelope illustratingthe manner in which itis opened.

Referring to the drawings in-detail whereout of the way.

in'like characters-of reference denote corres onding parts, thereference character 10 in icates the body of the envelope which'hasextending from one end what will be here- 'inaft'er' referred to asalong end flap, indicated at 11 Extending from the 0 posits end of thebod is a relatively short' up 12,

so that the en flaps are of unethual length, the construction of theenvelope ifiering in this respectfrom ordina envelopes. Extendingfrom-the lower. ge of the body is a bottom flap 13, while extending fromthe opposite edge is a closure flap '14-. Extending along the -outeredge of the 4 is designed tobe glued -to the-edge of the body by meansofthe adhesive indicated at A flexible wire or cordl'l is looped overthe end flap- 11 and may be arranged in the I or may be knotted orotherwise conn 7 asindlcated at 18 'ii em tively small flap being sealedalong its top with the ends twisted as shown at 19. The :35 12 is thenfolded over and glued to the y 10 along'the edges indicated at 20 and i21, the'last mentioned edge being glued upon 56 the cord so that thelatter is securely-held in place. The end 19 of the cord is preferablylooped as shown in Figure 4 of the drawings and the bottom flap '13 isglued tothe flaps 11 and 12 along the es 22 sotthat the20rd is held inosition with its ex remity projecting to orm a in portion. The closureflap 14 may t zl i ii bi closed in the usual manner.

By pulling outward u on the extremity of the cord, the end of t e envelomay be torn open as shown in Figure? 0 the drawiling:S without danger ofmutilating its con The opening'device or cord maybe located at eitherend of the envelope, but preferably at the end to which the stamp isaflixed, the cord being practically entirely concealed and The inventionis susceptible of various chan es in its form, proportions and minordetai s of construction and the right is herein reserved to. make suchchanges as properly fall within the scope of the appended claims. Q

Having described the inventionfwhat is claimed is: Y

1. An envelope comprising a body, an en of substantially the same sizeas the y and folded over upon the rear face of the utter, an attachingfla extending alon the outer edge of the en flan and folded inward andsecured, tothe ad'acent end f the body, a relatively small en flap extenthe end of the-body opposite thefirst "tioned snap and folded upon thelatte .a'flexible member looped over the first mentioned. flap andextendingdownward bep I if tween the flapsbelow the envelope, saidrelaand inner edge, a bottom .flap sealed .upon the end flaps andenclosing the ends of the lflexible member with the of the latterextending outward to provide; a grip from one odge'of the body.

An envelope comprising a and a closure flap exte flap fold'able on saidbod and reachin tothe opposite'end of said 0d when f0 ded thereon, asecond end flap f0 dable over the free end of thefirstnamed fie glue onboth 5 sides ofthe crease line made y folding the second flip securingthe body andfsecond named flap to the first named flap on opposite sidesthereof, a. flexible member 100 ed around the, freeend of the firstnamed up and r eured thereto by the second named end 10 flap,the body ofthe envelope and glue.

In testimony whereof Iaifix my signature.
